2. It is time for her _____(have) a Chinese class.

Answer 1

为你解答。
1. What should he (do，原形) to learn English well?
他应该做什么来学好英语？
解释：情态动词should后用动词原形。

2. It is time for her (to have，不定式) a Chinese class.
她到时间去上语文课了。
解释：It's time to do，到时间做某事了。

Answer 2

第一空填do，前面已经有should，属于情态动词，其后应用动词原形；
第二空填写to have，it is time for sb to do something , 是固定搭配。
it is time that ，that 后面接的从句应用原型，因为里面省略了should.
